I have to second the Take Five pattern. It is quick and I have made several of them. There are also two Take Five books that have lots of patterns.
A similar result can be done with a free pattern/video called Double Slice Layer Cake from Missouri Star. It calls for a layer cake, but I just made my own layer cake out of five fabrics. The end look is just about the same. Both end up similar to a Yellow Brick Road.
